Unheated Tanzanite — Ethically Sourced from the Merelani Hills of Tanzania

Tanzanite is a once-in-a-generation discovery—found in only one place on earth, the Merelani Hills of Tanzania. This gem carries a mood like no other: deep ocean blues, violet storms, flashes of teal and lavender, and even golden or mermaid hues in untreated stones. It’s a gemstone that feels alive—changing slightly with every shift in light and angle.

At Caleb B. Quashen International, we specialize in unheated Tanzanite—rare, untreated, and full of wild color stories that go beyond the typical. We work directly with partners on the ground in Tanzania, supporting small-scale miners and ensuring every stone is sourced ethically and respectfully.

Our Tanzanite Collection Includes

• Unheated stones in unexpected colors—green, peach, teal, mermaid, and vivid purples
• Precision and custom cuts—shields, pears, trilliants, and geometric ovals
• Natural crystals with full-spectrum zoning and individuality

Tanzanite is a gemstone of transformation. Of rare energy. Of moments you don’t want to forget.
